Recent queries about internal dimensions for sizing the
pcbs suggest that you should subtract about 2mm from the quoted external dimensions

Please note I do not make these boxes they are imported
from Germany to the UK and a custom box size requires a minimum order quantity
of 20 units, so this is generally not economical, unless you are marketing a
project.

Other sizes can be ordered to suit your requirements, please
ask. Please note it is easy to make boxes of a different,
shorter, length from these by pruning the long side wall. You are
of course left with a "too long" lid but at least you
have only one flange to fold to alter that, after cutting the lid
down. If fact, reforming the lid flange is not actually necessary
and the cropped lid can be secured with a couple of dabs of
solder.....not as pretty though....I am sure our German friends
would not approve !

Other sizes not stocked.....at present
...Please ask I can add your requirements to my next order

Masthead mounting enclosures (Schubert)
I am stocking two sizes of the Schubert Masthead enclosures, the Medium and
Large
These consist of a plastic "Hood" and "L" shaped base-plate
drilled for a mast clamp
self-tap screws, and a mast clamp Medium pictured below

Note that these can be supplied without the 60mm mast clamp for £13
and £23 respectively

Filter boxes (Popular
for G4DDK wideband pre-amps)

Filter boxes (Tin-plate). These come in two
sizes, they have the same width and height (20mm square) but are
available 37mm and 55mm lengths. They are pre-punched at both ends to take BNC connectors (with the
alignment "flat") and can be supplied as a kit with
either grounded or isolated BNC sockets (ask)
They are ideal for isolating transformers and small in-line
filters or attenuators, or even couplers !! These are
suggested for use with the wideband amp pcb kits that Sam G4DDK sells

Coax adapters. (new) These are not of the
highest quality but are adequate for most purposes, I suspect the
insulation is Polypropylene rather than PTFE
I am running these stocks down as they are not really microwave quality

I have a stock of Selectro plugs and sockets in SMB and SMC in sealed packets
please ask.

I have also some Reverse SMA (WiFi) to standard SMA adapters please ask these
are £4.00 each

Recent messages on the Yahoo group turned up the need for a LPF on the SG
Labs 23cm transverter. I have a stock of DB6NT 23cm LPFs which while intended for TX
1 up to 30 watts would provide this service as a "no-tune" solution. I
can also supply a basic kit which includes a 1000102 box and two SMA (F) sockets for
£30.00. The board (approx 35 x
72mm ) alone is £24.50 See the DB6NT web site for the details.

Illuminated Head-band Magnifier (marked
"Velleman" ), for those like me suffering eyesight
degradation, as a help to aid
in the fabrication of SMD populated pcbs. Two levels of
magnification, and a flip-down loup. I don't
bother with the battery illumination facility preferring to use a
desk lamp................................only...£7.00ea.

Quality 10MHz HC49/U crystal (Farnell part
103-887) 10ppm tempco ................................at £1.50ea.Though not cut for the appropriate temperature I am told these work
well in John 's OCXO

GPIB / HPIB / IEEE-488 stackable
interconnecting leads, There are used but visibly in good
condition though there may be
a little surface rust on some of the fixing screws. They are
"good makes" like IOTECH, Amplicon, RS Components etc.,
and all have a double ended connector at both ends. At this price
they are not electrically tested !!
0.5 metre length...............................£1.50ea
1.0 metre length...............................£2.00ea.
2.0 metre length...............................£3.50ea.
